BehaviorRelay is a wrapper for
`BehaviorSubject`.
Unlike `BehaviorSubject` it
can't terminate with error or
completed.
A mutable property of type
`Value` that allows observation
of its changes.

•This relase introduces new framework RxAtomic that enables using C11 atomic primities
•in RxSwift as a replacement for deprecated OSAtomic* functions.
Carthage users will probably need to include this framework manually.
•ɾUpdates deprecated OSAtomic* primitives to use C11 atomic primitives.
•ɾAdds Event, SingleEvent, MaybeEvent and Recorded conditional conformance
•ɹto Equatablewhere their Element is equatable on RXTest for clients that are using Swift >= 4.1.
•ɾAdds string to NSTextView.
•ɾConsolidates per platform frameworks to multi-platform frameworks.
•ɾXcode 10.1 compatible.
